How can I add a operation level handler in Axis2

Question

Hello,

I'm using the Axis2 Java web service engine and have written a server side handler for handling security for our application. The handler gets called when configured globally in axis2.xml, but doesn't get called when I apply it selectively on a per web service operation level.

Here's a snippet from my services.xml where I tried to add my handler:

<operation name="UpdateItemLocation" mep="http://www.w3.org/ns/wsdl/in-out" namespace="urn:acmetechnology:dm:wsdl">

UpdateItemLocation urn:acmetechnology:dm:wsdl:DMWebServicePort:UpdateItemLocationResponse

Do I have to create a module in order to do this? If so, what would what the services.xml look like and how do I make sure the module is engaged, etc?

Thanks.
